We will present the current voltage characteristic for DC to low frequency operation of the Enhancement type MOSFET. Circuit Symbol Figure 4.10 (a) Circuit symbol for the n -channel enhancement-type MOSFET. (b) Modified circuit symbol with an arrowhead on the source terminal to distinguish it from the drain and to indicate device polarity (i.e., n channel). (c) Simplified circuit symbol to be used when the source is connected to the body or when the effect of the body on device operation is unimportant.
